TROLLEY GUARD AND GUIDE.

Specification of Letters Patent.

Patented June 30, 1908.

To all whom it may concern:

Be it known that 1, CHARLES LATSOH, a citizen of the United States,residing at Cleveland, in the county of Ouyahoga and State of Ohio, haveinvented certain new and useful Improvements in Trolley Guards andGuides, and do declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to trolley guards and guides, and the object of theinvention is to provide a guard which will prevent the trolley wheelfrom umping off the wire, and ifit should ha pen tovget oil that theguide mechanism wi assist in restoring the wheel to the wire, allsubstantially as shown and described and particularly pointed out in theclaims.

In the accompanying drawings, Figure 1 is a side elevation of a trolleywheel harp or support and the wheel, and my new and original guard andguide mechanism thereon. Fig. 2 is a front elevation of the said parts,showing them closed in full lines, as in action, and in dotted lines asthey appear when the guard is opened to restore the wheel to the wire.

A represents an ordinary trolley pole and B the harp orwheel support atthe top thereof, in which wheel O has any suitable bearings.

D represents a pair of guard members or arms which are supported in avertical position or relation on opposite sides of the axis or center ofwheel 0 by means of a special arm E, fixed on pole A by means of clampH, or its equivalent, and having said guards D pivotally supported sideby side on the outer end thereof. A suitable spring or springs J arefixed on the said arm E in such relation to guards D as to exert anupward and inward pressure thereon, thereby holding said guards togetherin working relations at their top or upper ends relatively as seen infull lines, Fig, 2. To this end, also, the said guards are curvedbetween their ends to adapt them to extend around wheel O and meet, orapproximately meet, over or above the wheel. Actual meeting or contactbetween the said parts is efl'ected through rollers or wheels L, whichhave short spindles 2 at their bottom set vertically in suitablebearings in the extremities of said guards and adapted to hear oneagainst the other at their edges under all normal conditions and thusclose line wire N within said guards and guard rollers. The position ofthe rollers on the guards is horizontal when the trolley is in use, andthe bottom sides of the rollers are flat and flush with each other.Rolling members like L, or their equivalent are necessary to pass thefrequent suspensory wires which carry wire N and which pass be tweensaid rollers as the trolley follows the wire, the rollers turning andseparating enough to let them pass. Then again there are plates or frogsencountered where roads intersect or diverge and which requireadaptation of my guard thereto. To this end I have placed s hericalrollers or balls 5 in the top of rol ers L and which are free to turn inany direction therein as they contact with such plates or frogs.

Trolley cord P is divided at its upper end and extends to guard arms Dnear their middle so as to get a grip thereon to pull them apart attheir top when for any reason it becomes necessary to place the trolleyWheel on the wire. This lateral pull on said arms is against spring J toposition dotted lines, Fig. 2, as the maximum, the function of saidspring being to hold arms D in working position. Hence if the trolleygets oil the wire and guard members D are spread to get it back, theguides 7 will help to guide the wire back to the wheel. The guardmembers D and their supporting arm E may be attached to trolleys ingeneral use and are a separate article of manufacture and sale.

What I claim is 1. A trolley harp having a trolley wheel mounted thereinand a pole supporting the harp, in combination with an arm fixeddetaohably on said pole and extending beneath said wheel, a pair ofguard members pivotally supported from said arm across the axis of thetrolley wheel, rollers mounted in the free ends of said guard membersand arranged to meet over the trolley wheel, springs to hold said armsin working position,

and guards on the trolley harp bridging the space at each side betweenthe trolley Wheel and the said rollers.

2. A pair of guard members for trolley Wheels having rollers adapted tocontact at their periphery and bearing balls mounted in the top of saidrollers and free to turn therein.

3. The combination of the trolley support and trolley Wheel therein,with hingedv side 10 guards having rollers in their upper ends over saidWheel and bearing balls freely mounted in the top and center of saidrollers and extending above the same.

In testimony whereof I sign this specification in the presence of twoWitnesses.

CHARLES LATSOH.
